Okla. Stat. tit. 63, § 63-1-731.3: Detectable heartbeat – Abortion prohibited

A. No person shall perform or induce an abortion upon a

pregnant woman without first detecting whether or not her unborn

child has a heartbeat. No person shall perform or induce an

abortion upon a pregnant woman after such time as her unborn child

has been determined to have a detectable heartbeat except if, in

reasonable medical judgment, she has a condition that so complicates

her medical condition that it necessitates the abortion of her

pregnancy to avert her death or to avert serious risk of substantial

and irreversible physical impairment of a major bodily function, not

including psychological or emotional conditions. No such condition

may be determined to exist if it is based on a claim or diagnosis

that the woman will engage in conduct which she intends to result in

her death or in substantial and irreversible physical impairment of

a major bodily function.

B. A "detectable heartbeat" shall mean embryonic or fetal

cardiac activity or the steady or repetitive rhythmic contract of

the heart within the gestational sac.

C. "Reasonable medical judgment" means a medical judgment that

would be made by a reasonably prudent physician, knowledgeable about

the case and the treatment possibilities with respect to the medical

conditions involved.

D. Any person violating subsection A of this section shall be

guilty of homicide.
